A HYDRAURIC HOIST WHICH IS CONTROLLABLE WITH REGARD TO POSITION AND APPLIED FORCE FOR TRACTORS AND AGRICULTURAL MACHINES AND DISTRIBUTOR THEREFOR

摘要

The invention tractors and as in consideration of the applied force and the position of the agricultural machine according to a distributor for a controllable hydraulic hoist, at least one inlet conduit (3), at least one discharge duct (8, 22, 11, 19a) for a pressurized fluid and it includes a compact body 2 which ridorok lift the hoist equipped with at least one conduit (5) connected to the hydraulic cylinder (6). May regulate the flow of pressurized fluid and the valve unit (12) for discharging the fluid coming from the duct 5, the valve means 7 and the hydraulic lifting cylinder (6) in communication with this, is arranged in the body 2 of the distributor . Slider 16 with respect to the neutral position, two corresponding directions (C, S) with the inner surface to movement possible and preferable in using the outlet valve means (16c), the control valve means hydraulically in the cylindrical body (2) and controls (7). And also the slider 16 is controlled by a variable choke member (16c) and discharge valve unit arranged in the main internal duct (9a, 9b).
